Soldering LED's for climate control color change..., two aren't lighting up... Options

[jophish]

So i'm in the process of changing the interior lights of my car, got everything done except the climate control unit, which is currently sitting in pieces right next to me. Now i've gone in and soldered blue LED's onto the terminals where the green ones used to be (i'm talking about the ones hard wired in to the board, not the twist in lights). The only issue is that only 6 of the 8 lights are lighting up. The only ones that aren't are the one for the windshield defroster, and the one for the AC...the polarity matches that of the LED's that i clipped off before, so i dunno what's up. Are they on a different circuit that requires another part of the unit to be plugged in?

If anyone has any experience with this sorta thing some assistance would be great....i'm so close to getting this project done.

the LED's are all on the same harness...the defroster that's not lighting up is the one for the front windshield, the rear defroster unit actually came out amazing, put a blue LED in the bottom and changed the orange LED to red. Originally, i clipped the LED for the AC first and tested it out...nothing doing, but i used the same LED to replace another one and it works, which leaves me baffled as to why those two don't work...
